Semantic Coherence โ€” The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Semantic drift cannot be measured traditionally because there is no homepage signal to compare against sub-page substance. The H1 is empty and the meta_description is missing, creating a total disconnect between the domain’s implied purpose and the actual content delivery. This represents a catastrophic failure of messaging consistency where no value proposition is established across any analyzed slot.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
